Does anyone care to venture an opinion about the current value of WWII vintage boxed 00 buck ammo?

Maybe $100 for the 25 round US Property marked boxes of commercial, paper cased 00 buck in excellent, undamaged condition and double that for the fully wrapped boxes of Winchester or Remington brass cased ammo in the same shape?

I have not seen any of it change hands online in a good while and I have not been to any recent quality collectors shows. All thoughts or opinions appreciated.
